Construction & HVAC
Construction and building trades require skill, knowledge and experience to deliver solid results. Weather can negatively
affect even the best laid work plans. Kestrel Weather & Environmental Meters allow you to account for environmental conditions that cost you time, money and labor.
Crane Operations
Strong winds impose additional loads on mobile cranes and affect
stability. Exceeding the manufacturers’ stated wind speed limits can result
in damage to the crane, or worse, surrounding structures and workers. In
cold conditions, the Kestrel Meter gives the vital temperature and wind
chill data needed to assess shock loading, crane hydraulics and derating
of the crane as well as the safety of the personnel working in the cold
conditions.
Concrete Placement
Plastic shrinkage cracks occur when the surface of the concrete dries
rapidly and shrinks before it can gain sufficient tensile strength. When
ambient conditions and concrete temperatures combine to produce
conditions that create a high evaporation rate, the chances of the surface
drying prematurely and shrinkage cracks forming increases. Use a Kestrel
3000 to measure the relative humidity, ambient temperature and wind
velocity right where the concrete is being placed, then calculate the
evaporation rate using reference charts. Even better, use a Kestrel 4300
and get a direct readout of evaporation rate. Either way, taking the steps
needed to prevent plastic shrinkage cracking can save you thousands of
dollars, and your reputation.
Steel Bridge Coating & Lining
Bridges and other large steel structures are painted with coatings that
protect the integrity of the steel and prevent corrosion. It is critical to
monitor ambient temperature, relative humidity and dewpoint as well as
the surface temperature of the steel to ensure good adhesion and proper
curing. A Kestrel Meter does the job.
Scaffolding
Monitoring the wind speed and wind direction at the job site is
required by industry standards including OSHA and ANSI.
Excessive wind speeds can cause equipment and property damage, injury
and even fatality. With a Kestrel Meter, you can easily monitor and record
all relevant job site environmental conditions. For a small price, you can
avoid the high cost of a scaffolding accident on your watch. Monitoring
the wind is not just your responsibility – it’s your liability.

Heating, Ventilation, Air
Conditioning & Refrigeration
HVAC/R system commissioning and verification can determine that a
system is working correctly, or can identify a problem area in a faulty
system. Volume air flow is a calculation based on the air velocity
and the dimensions of the flow opening, and it’s one of the most
important measurements HVAC/R professionals require. The Kestrel
4200 automatically calculates air flow in CFM, making the technician’s
job easier and faster. Because it also measures the moisture content of
the air, it is quickly becoming an essential piece of equipment for the
dehumidification and mold inspection and remediation professional as well.
Home Inspections
A large portion of any home inspection will be dedicated to examining the
heating and air conditioning systems. Quickly checking the consistency
of warm and/or cool air in each room is as easy as entering volume and
the duct size and holding a Kestrel 4200 in the air flow. The 4200 also logs
data with the press of a button, allowing home inspectors to save data and
review it back at the office when writing up their report.
Industrial Hygiene
Industrial hygiene professionals aim to monitor and protect the health
of workers and the community. Kestrel Weather & Environmental Meters
enable industrial hygienists to do just that by providing accurate, reliable
information on field conditions. Kestrels are used to evaluate ventilation
in hazardous materials remediation (e.g. asbestos abatement and
mold remediation) where contractors must set up negative pressure
containments using HEPA-filtered fan units.

Viticulture
FARMING & Agriculture
In a regulation-intensive activity, the Kestrel helps you ensure compliance. Relative humidity,
wind speed and wind direction are all critical measurements for ensuring safety and
effectiveness in farming and agriculture. Minimize waste and maximize your productivity with a
Kestrel Meter.
Spraying
The Kestrel’s accurate wind speed readings ensure safe and effective spraying during appropriate
weather conditions. Many locales have regulations specifying maximum permitted wind speed
when spraying to minimize spray drift. In hot, dry conditions, evaporation can send your expensive
chemicals uselessly into the air rather than onto your crops. Selecting an appropriate nozzle and
increasing the spray droplet size can minimize costly evaporation.
Barn Ventilation
Vineyard managers can monitor the weather right at the
individual vine. In the spring and fall, knowing the temperature
trends and dew point is critical to determining the need for frost
protection. In the summer, being able to track solar radiation
and sun exposure is key. Tracking conditions at potential vine
locations can help you develop an accurate understanding
of your property’s microclimates and select the varietals and
growing sites that will ensure success year after year.
Crop Harvesting
Keeping an eye on the current and developing environmental
conditions can help farmers determine the best time to harvest.
Whatever your crop, a Kestrel Weather & Environmental Meter
makes it easy to monitor field conditions real-time to ensure
selection of the ideal conditions for maximizing your harvest
and crop quality.
Livestock Temperature
Monitoring
Heat stress can reduce productivity and even cause death
in livestock. By using a Kestrel to monitor temperature and
humidity, and referring to the heat index appropriate for their
livestock, farmers can take appropriate cooling measures in
time to prevent sickness and loss.
Golf Course Management
& Landscaping
The Kestrel is the perfect tool to get an accurate assessment
of air movement, which is vital for healthy turf in areas where
surface cooling is needed. Proper air movement reduces leaf
wetness and decreases the likelihood of fungal diseases. A
constant air movement of just 3 mph coupled with adequate
soil moisture can reduce the need for pesticide use and keep
turfs up to par.
Proper ventilation, temperature and humidity control of livestock facilities can reduce disease
and prevent stock loss as well as improve your rate of gain and feed-conversion efficiency. Measure
the conditions that matter most – right where your stock are experiencing them.
Irrigation Audits
Inefficient irrigation systems are costly: they waste water, wash off fertilizers and lawn chemicals,
and degrade sidewalks and roads prematurely. The ultimate tool for irrigation audit monitoring is
the Kestrel 4500 together with a tripod and Kestrel vane mount. The data log is ideal for use in the
field, and wireless Bluetooth® data transfer capabilities makes log entries and report development
a snap back in the office.

Hunting
When the weather changes, so does your game. As a hunter, you’re used to waiting –
a Kestrel can help you be sure you’re waiting in the right place at the right time. Barometric
pressure and wind direction readings give you the ultimate advantage on your hunt.
Animal Behavior
The wind speed affects how well animals can hear and smell, causing them to be less active as wind speeds increase. Temperature
influences animals’ comfort, restricting their activity if it’s too cold or warm. For most game, activity levels will rise or fall along with the
barometric pressure. A Kestrel Weather & Environmental Meter can track weather trends and give you current conditions to plan when
and where to hunt.
Bow Hunting
The large side surface area of an arrow makes it far more subject to wind drift than other hunting projectiles. Even 5-10 MPH of
crosswind requires wind compensation or arrow selection adjustment. The Kestrel calculates the exact crosswind with respect to a
target direction – invaluable when practicing and learning how to read the wind.

with a Kestrel Weather & Environmental Meter.
Paranormal Investigations
When investigating activities unseen to the naked eye, only a
Kestrel Meter can accurately detect the slightest fluctuations
in the immediate environment. Paranormal investigators are
concerned with monitoring sudden changes in conditions,
such as wind, barometric pressure and temperature. Waterproof
and extremely rugged, Kestrel Meters are as fearless of harsh
environments as the ghost hunters who use them.

Volume Air Flow (CFM): The volume of air moving through a
area of the opening times the air velocity.
HI
B
Wind Direction: The direction from which the wind
is blowing, expressed as a compass point or degrees. Bearing may be
reported in true or magnetic.
DP
Cross Wind: The component of the wind blowing at right angles
WB
to a given direction of travel, such as an aircraft or bullet’s line of
flight, calculated by multiplying the wind speed times the sine of the
angle between the wind and the direction of travel.
Head/Tailwind: The component of the wind blowing against
(headwind) or with (tailwind) a given direction of travel, such as an
aircraft or bullet’s line of flight, calculated by multiplying the wind
speed times the cosine of the angle between the wind and the
direction of travel.

for a given humidity, temperature and wind speed. Evaporation rate is a
critical environmental indicator that concrete contractors use to ensure
they avoid plastic shrinkage cracks in concrete installations especially
concrete flatwork.

dry bulb temperature (in degrees C). Delta-T offers a quick guide to
determining acceptable spraying conditions or ideal spray nozzle.
Barometric Pressure: The atmospheric pressure of the weight of
DP
in relation to the relative humidity, used as an indicator of the
perceived temperature.
HR
Relative Humidity: The ratio of the amount of water vapor in
the air at a specific temperature to the maximum amount that the air
could hold at that temperature, expressed as a percentage. Relative
humidity is a function of temperature and therefore changes as the
temperature changes, even if the amount of moisture in the air
remains constant.
HR
HR
Dewpoint: The temperature at which the water vapor in the atmosphere
begins to condense. Any further cooling causes condensation (fog and dew).
This is also the temperature of saturation.

measurement of naturally aspirated wet bulb, globe temperature and dry
bulb temperature. This environmental temperature data combines
temperature, humidity, wind speed and thermal radiation to access
heat stress.
Thermal Work Limit (TWL): TWL uses environmental
measurements, including thermal radiation, to predict work limits for people
exposed to heat stress.
Absolute Pressure: The actual measured pressure of the weight of
air above the measurement point. Also called station pressure.
D
Wet Bulb Globe Temperature (WBGT): WBGT is a composite
DT
the air above the measurements point, reduced to
sea level. Also known as mean sea level pressure.

HR
HI
ambient temperature of the air and water vapor as measured by a
thermometer or other measuring device in which the thermal element is dry and shielded from radiation. Water and snow temperature are measured with a measuring device in direct contact with
the environment. Available units are Fahrenheit – a temperature
scale where water at sea level has a freezing point of +32° F°, and
a boiling point of +212° F; and Celsius – a temperature scale where
water at sea level has a freezing point of 0° C and a boiling point of
+100° C.
B
Density Altitude: The equivalent altitude in the ICAO standard
reference atmosphere for the measured temperature, relative humidity
and air pressure. A measure used primarily by pilots, high-performance
engine mechanics and long-range shooters.

When conditions are hot, stay one step
ahead of heat stress.
Human heat stress results from a combination of many environmental factors – air temperature and
humidity along with radiant heat from the sun and surfaces, balanced by the cooling effect of breezes or
air flow. The Kestrel 4400 Heat Stress Tracker employs the most common composite measurement used to
determine appropriate exposure to heat stress conditions — Wet Bulb Globe Temperature (WBGT).

Bluetooth® Wireless Data Transfer
Kestrel NV:
Instant Weather Data to any Bluetooth® Device
As Rugged as the Environment.
As Stealthy as the Mission.
Due to overwhelming demand from our military customers, the
Kestrel NV line was born. Military personnel and pilots flying in
darkness are often concerned with preserving their night vision
and secure position. The NV model has the same features as its
more colorful counterparts, but is olive drab or desert tan (4000,
4400, 4500, and 4600 models only) with a reduced brightness
red-toned backlight that helps protect the user’s adapted night
vision. (It takes 30 to 45 minutes for the average eye to adapt
to darkness and maximize night vision. Even a short burst of
white, yellow, green or blue light “bleaches out” the rod cell
photoreceptors in the eye and causes night blindness until
the entire adaptation process can take place again.)The dim
backlight is also much more difficult to detect with the naked
eye in night or covert operations.
Kestrel meters with integrated Bluetooth® wireless data transfer
offer the ultimate in portable and accurate environmental data.

Bluetooth® data transfer is available throughout the entire
Kestrel 4000 series, including specialty Kestrel units.
(The NV backlight appears soft greyish pink, and is still in the
visible spectrum, so it is not compatible with night-vision
equipment.)

Now, both real-time and logged data can be transferred
wirelessly and automatically, making a Kestrel 4000 series
weather meter the perfect tool for virtually any job that
requires quick and reliable weather data – Bluetooth® data
transfer technology eliminates the need for a separate
interface and cabling.

NIST-TRACEABLE ACCURACY
calibration SERVICES
Each Weather Meter and wind impeller is individually tested
and calibrated for every single measured value before it leaves
our factory. Wind impellers are tested in our wind-tunnel
at low and high speed and their startup speed is verified.
Relative humidity models receives a two-point calibration in
humidity and temperature controlled chambers monitored
by a highly accurate dewpoint hygrometer. Temperature and
pressure are both verified against calibrated standards. Each
of our primary standards used in calibration is traceable to
the National Institute of Standards and Technology (NIST).
Our primary Calibration Standards are sent for calibration on
a regular schedule, and only approved laboratories and NIST
themselves are used for calibration. Every Kestrel includes a free
Certificate of Conformity detailing our testing procedures and
specifications.
Customize your kestrel
We offer multiple levels of calibration services to
meet your needs. With our most affordable basic
calibration, we repeat every calibration step used
when your Kestrel was manufactured and reissue
your unit’s Certificate of Conformity. We can
provide NIST-traceable Calibration Services with
full documentation of as-found and as-left values
as well as verification at customer-designated
points. We even offer “tune-up” services including
replacement impellers and batteries.
NK features a branding and customization program for Kestrels
Meters, allowing you to create a unique and high-value sales
tool or customer incentive. Options include: case color; custom
window with your company’s logo; custom pad print a message

WARRANTY
Made in the U.S,A.
kestrel five-year Warranty
We understand that Kestrel Meters are used to help people do their jobs more efficiently, and that reliability is paramount. Kestrel Meters are trusted
by wildland firefighters, scientific researchers, professional meteorologists, first responders, HAZMAT teams, and even the US Military. We know they
don’t lead a pampered life, and we design them for years of performance in tough conditions. Every Kestrel Weather Meter is built in our manufacturing
facility in Boothwyn, Pennsylvania, and tested multiple times during and after assembly for function, sealing and appearance. We guarantee every Kestrel
product to be free of defects in materials and workmanship for a period of FIVE YEARS from your date of purchase. We will repair or replace any defective
product or part when notified within the warranty period, and will return the product via domestic ground shipping at no charge.
The following issues do not result from a manufacturing defect and are not covered under this warranty:
● Damage resulting from severe impact, crushing or intentional mechanical harm
● Modifications or attempted repairs by someone other than an authorized NK repair agent
● Normal wear from use of the product
● Failed batteries and/or battery corrosion damage
● Re-calibration beyond 30 days from your date of purchase
Your warranty period will be measured from your date of purchase. The best way to ensure full warranty coverage is to REGISTER your Kestrel Meter
promptly via NK’s website). We keep your registration information strictly confidential and do not sell it, share it, or use it for anything but productrelated information bulletins (which you may decline receiving).

There are many legal and regulatory standards for determining
country of origin of a product. What does NK mean when we say
“Kestrel Weather and Environmental Meters are designed and
manufactured in the USA”?
· NK employees all work together in our single-location factory in southeastern Pennsylvania to research, design, build, test, calibrate, market, pack, ship and support NK’s products, including Kestrel Weather and Environmental Meters.
· We purchase many of our components from US partners, including:
• All of our injection molded parts
• All of our product labeling, nameplates, panels, packaging Of course, the majority of the electronic components
contained in a Kestrel meter originate from overseas in Europe
(precision sensors) or Asia (displays, circuit boards and micro
components), where virtually all of such components are
now fabricated. We select these components for optimum
performance and reliability, not country of origin.
Every Kestrel meter qualifies for preferential treatment under
the NAFTA under both the change in tariff classification and
regional value-content requirements of Preference Criterion
B. Every Kestrel meter also meets the requirements of the
Buy American Act because more than 50% of the cost of its
components is produced or manufactured in the United States.
and printing
• Berry-compliant options for cases and sewn accessories
• Precision machined metal parts
• Batteries
· When we do partner with outside resources for software or industrial and mechanical design, we generally work with US companies, although we enjoy some long-standing relationships with global engineering partners which are particularly helpful when complying with export regulations.
· We actively support US manufacturing through Lean continuous improvement of our processes, as well as sharing of best practices with other companies seeking to do
the same.

Measure of human heat stress defined as the combination of effects due to radiation, convection, and conduction. Outdoor WBGT is calculated from a weighted sum
of natural wet bulb (Tnwb), globe temperature (Tg), and dry bulb temperature (Td). User settable on-screen warning zones. 4400 and 4600 only.

Similar to psychrometric wet-bulb temperature (see below). However, Tnwb only undergoes forced convection from the ambient air velocity. Tnwb is a measure of the
evaporative cooling that the air will allow. This is accounted for by combining the effects of, mainly, relative humidity and windspeed. 4400 and 4600 only.

The rate at which moisture is lost from the surface of curing concrete. Requires user measurement and entry of concrete temperature obtained with an accurate IR or
probe thermometer (°F or °C, not included). Readings should be taken 20 inches above pour surface with the thermistor shaded, and averaged for 6-10 seconds using
built-in averaging function. 4300 only.

Evaporation Rate
Effective wind relative to a target or travel direction. Auto-switching headwind/tailwind indication. 4500 and 4600 only.
Temperature indicated by a sling psychrometer. Due to nature of the psychrometric ratio for a water-air system, this approximates the thermodynamic wet-bulb
temperature. The thermodynamic wet-bulb temperature is the temperature a parcel of air would have if cooled adiabatically to saturation temperature via water
evaporating into it.
Perceived temperature resulting from combined effect of wind speed and temperature. Calculated based on the NWS Wind Chill Temperature (WCT) Index, revised
2001, with wind speed adjusted by a factor of 1.5 to yield equivalent results to wind speed measured at 10 m above ground. Measurement range limited by extent of
published tables.
